Actually, that was one of the shots I took to illustrate the fact that occasionally the 3D Lights utility doesn't work as well as it should, which is why some of the lights aren't kicking in properly. But the thing with that utility, is that you can add them wherever you like on an aeroplane via the config file just like the normal lights in FS, as they are simply another light FX file in the program.
In any case, the lights on the default FSX Airbus are the least of its problems - when FSX first came out, I showed one of my friends who is a designer for Airbus Industrie the climb rate on that thing, and he was laughing his ass off at how inaccurate it was. It goes up like an F-104.
